Thread: why Torque MGT pull Timing

  1. #1

    why Torque MGT pull Timing

    1971 Chevelle Stock Ls3 4l80e

    The car runs grat but sometimes pull Timing at Wot.

    In the Scan I see that the Torque MGT is active.

    I have taken out all known torque limits.

    You can see in the scan the first two Wot runs are good.

    Ane the last two pull timing but why?

    Thanks for Help

    I would think that it would be something to do with your torque reduction in the trans because it's still active 15417 / 15418.

    Okay I thought that he only reduces the shift torque


    @ 10,22 in the scan the Timing goes down to 4 degrees.

    and @ 11.16.


    thanks
